    摘要： There is proposed a structural junction (11) in an aircraft or spacecraft fuselage (2), comprising a first fitting (13) attached to a portion (17a) of a fuselage skin (17) in a first fuselage section (2a), a second fitting (23) attached to a portion (17b) of the fuselage skin (17) in a second fuselage section (2b), and a pressure bulkhead skin (19) attached to an inner flange (29) of the first fitting. The inner flange is spaced apart from the fuselage skin towards an inner space (10) of the fuselage. The first and second fittings are connected or configured for being connected at least using a plurality of tension bolts (37). The tension bolts each are arranged and adapted to transfer at least tensile loads, in a direction across adjacent edges (12a, 12b) of the first and second fuselage sections in a region where the first and second fuselage sections are joined, between the first and second fittings. Furthermore, the invention relates to an aircraft or spacecraft (1) comprising a fuselage including such a structural junction, and to a method of forming a structural junction in an aircraft or spacecraft fuselage. The invention may in particular contribute to reducing the number of parts and the assembly lead time during fuselage section assembly and to improving ergonomics during the assembly process.

    摘要： The invention relates to a device (10) for attaching an object (91) to an attachment rail (15), in particular a seat rail in an aircraft or spacecraft (1). The device comprises a base part (21) having a support surface (22) adapted to be placed onto an outer surface (16) of the rail (15), and a locking element (28) adapted to partially protrude from the support surface (22) along a line of protrusion (36). The base part and locking element are coupled or configured to be coupled in such a manner that the locking element can be moved relative to the base part along the line of protrusion (36) and rotated with respect to the base part. An end section (29) of the locking element has a tip portion (30) shaped in a dovetail-type manner. The device comprises a tensioning arrangement (45) for tensioning the locking element with respect to the rail. Furthermore, the invention relates to an arrangement (100) comprising such a device (10) as well as an attachment rail (15) comprising a rail main body (50) and a plurality of bushes (55). Moreover, a method for attaching an object, and a seat rail are proposed. The invention may contribute to attaching the object reliably and rapidly, and may in particular be useful for preventing corrosion of attachment rails in a cost-effective manner.
